KARL E. GARLING, OF NEW YORK, N. Y.

Application filed April 5,

T 0 all whom it may concern Be it known that I, KARL E. GARLING, a citizen of the United States, and residentof New York city, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in an Electric Neutralizer and Drier for Printing Presses, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to control the fuel supply for an apparatus of the character mentioned in correspondence with the operation of the mechanism of the press with which it is associated; to make the operation of the neutralizer dependent on the operation of the mechanism of the printing press with which it is associated; to avoid operatin the neutralizer when the paper upon which it is operating is stationary; and to provide automatic means for discontinuing the flame neutralizers employing such coincidently with the discontinuance of the feed of the paper of a printing press with which the neut-ralizer is associated.

Drawings.

Description.

Heretofore, apparatuses employing heat for drying the ink on printed sheets and for neutralizing the static electricity associated Specification of Letters Patent. Patented Apr. 25, 1922.

therewith, have been constructed and arranged various forms. Certain of the apparatuses have made provision for discontinuingthe heat when manually operated to that effect and certain apparatuses have provided means for discontinuing the heat when the press has ceased to operate. Difliculties have arisen in the use of the manually operated apparatuses owing to the liability of neglect or inattention by, or on the part, of the attendants on the press. Difficulties have also arisen in the use of the automatic mechanisms owing to the liability of the same to fail in operation'at critical moments, and to the slowness with which the said apparatuses usually work.

Those apparatuses which employ electricity as an actuating means are further liable to failure owing to the fact that the electrical supply is oftentimes uncertain andvariable. The present apparatus overcomes the various difficulties mentioned by employmg a rotary valve 10, located on the supply pipe 11 of a fuel gas line, and by providing said valve with a gear-toothed pinion 12, with the teeth .whereof, a rack 13 is engaged.

As seen best in Figure 2 of the drawings, the rack 13 is extended from the end of-a plunger 14, which is reciprocatively mounted in a tubular bushing 15. The bushing 15 is adjustable in a tubular casting 16, formed at the end of a bracket 17. The bushing is held in adjustment by a set screw 18. The upper end of the bushing 15 has a flange 19 which forms a bearing for the plunger 14, and with the flange 20. A washer 21 co-operates with the flange 20 to house the ends of the arms 22 of rocking bell crank levers 23.

The bell crank levers 23 are pivoted on pins 24 which extend between upstanding lugs 25,

erected on a box-like body 26. Pendent from the underside of the body 26 is a pulley 27 adapted to receive, in operative relation, the belt 28, to be driven thereby.

The belt 28 engages, and is driven, by a pulley 29 suitably located on a driven or driving shaft 30, of the printing press mechanism. The pulley 29 is adjustably mounted on the shaft 30, being held in any position thereon by the set screw 31. I

To adjust the working position of the body 26, pulley 27, and parts connected therewith, a collar 32 is mounted on the bushing 15, a set screw 33 serving to hold the said pulley in adjusted relation to'the said bushing.

It will be observed that by means of the screws 18 and 33, the bushing .15 may be adjusted so that the inoperative position of the plunger 14 may be determined, to provide more or less lost motion for the valve 10, to make the mechanism more or less sensitive in its operated effect on the said valve. This 7 is accomplished by raising or lowering the flange 19 which forms a seat for the flange 20, thereby determining the inactive position of the flange 20, and plunger 14, and rack 13 associated therewith.

By raising or lowering the collar 32, the initial operative position of the arms 22 of the levers 23 is pre-determined The levers 23 are actuated by the weighted balls 34. The balls 34 litre attached to the arms 23 and are normally overbalanced, asseen in Figure 2 of the drawings, to fall toward the center or the apparatus. The limit of the travel in either an inward or outward direction is determined by a pin 35, which extends between the lugs 25 to engage and arrest the movement of either the upwardly extended arm of the levers 23 or the horizontally extending arms 22.

From the position of the balls 34, it is evident that when the pulley 27 is rotated, the centrifugal force exerted upon the said balls will spread the same rocking the levers 23 on the pins 24 to lift the ends ot' the arms 22, the washer 21, plunger 14, and rack 13. .By reason of the rack 13 and the pinion 12, the latter is rotated to turn the valve 10 for opening the passage in the pipe 11, to permit the gas to flow therethrough to the flexible tube 35 and mixing chamber 36 connected therewith.

The mixing chamber 36 is provided with the usual air inlets 37, whereby atmospheric air is mixed with the fuel gas for consumption in the burner tube 38. The burner 38 has a series of jet openings 39, from which the flame is emitted in uxtaposed relation to the sheets of printing matter which are passed above the burner 38 bythe operation or the printing press with which the said apparatus is associated. A pilot tube 40 is furnished with a shield 41, which protects the flame of the said pilot during the inoperative moments of the apparatus.

Tt will be understood that the flame furnished by the pilot 40 is continuous, so that when gas is permitted to flow to the burner 38, the gas will be ignited on passing out on the burner openings 39.

To install an apparatus of the character described in operative relation to a print- 1 press, the pulley is disposed on any convenient shaf mechanism, which r driving mechanism o- The size 0 needs of installation. When this has oi the printing press I whenever the press operates.

lire pulley is determined by the movement or said centri been effected, the bracket 17 is secured by means of the bolt 42 to any convenient stationary member of the frame 43, said member being adjacent to the supply pipe 11. The supply pipe 11 is bolted by means of the loop 44 on a bench extension 45 of the bracket 17. The belt 28 is adjusted to the pulleys 27 and 29 and the mechanism is in condition to operate.

It is evident that if, for any reason, after the installation of the herein described apparatus, the printing pressis stopped, the valve 10 is immediately closed by the depression of the rack 13, which is lowered by the balls 34, falling toward the center of the body 26, thereby depressing the free ends of the arms 22 and parts connected therewith. The valve 10 being completely closed by this operation, the fuel supply for the heater 38 is automatically and positively determined.

Duringthe suspension of supply to the heater 38, the flame is maintained in the pilot 40. Danger from this flame is avoided by the shield 41.

When now the repair or other cause for the suspension of the operation of the printing press has been made or removed, and the press mechanism is again started, the pulley 27 is rotated with the result that the balls 34 are spread to lift the rack 13 and through the operation thereof on the pinion 12, open the valve 10 to permit gas to flow through the pipe 11, mixing cham ber 36, to the heater 38, where it is ignited by the flame of the pilot 40, when emitted through the burner openings 39.

From the foregoing, it will be seen that an eflicient and safe control is provided for a neutralizer and drier employing an exposed flame having a fuel gas supply.
